    Freezing transition of the vortex liquid in a layered superconductor
    (Elsevier Science Publishers B.V., 2001) Davoudi, B.; Kohandel, M.; Tanatar, Bilal
    The self-consistent theory of Singwi, Tosi, Land, and Sjolander is used to describe the liquid-solid phase in a layered superconductor in the limit of weak interplane correlation effects as would be applicable to BSCCO materials. We calculate the local-field corrections, static structure factor, and pair correlation function and compare our results with other methods. The Hansen-Verlet criterion is used to estimate the freezing temperature of the vortex system.

    Hard-core Yukawa model for charge-stabilized colloids
    (American Physical Society, 2000) Davoudi, B.; Kohandel, M.; Mohammadi, M.; Tanatar, Bilal
    The hypernetted chain approximation is used to study the phase diagram of a simple hardcore Yukawa model of a charge-stabilized colloids. We calculate the static structure factor, the pair distribution function, and the collective mode energies over a wide range of parameters, and the results are used for studying the freezing transition of the system. The resulting phase diagram is in good agreement with the known estimates and the Monte Carlo simulations. ©2000 The American Physical Society.
